Authorities have arrested a man in connection with the 2015 bludgeoning death of Lois Colley, the Westchester County socialite with ties to the Kennedy clan.

Colley, 83, was found lifeless on the floor of a laundry room inside her $25 million hilltop estate by a caretaker on November 9, 2015, police said at the time.

There were no signs that anyone had forced their way into the home. A small fire extinguisher was missing from the home; investigators said Monday they believe that to have been the murder weapon.

Gomez was recently found in Cancun, Mexico, then deported to Guatemala before being brought to the U.S.to face charges. But because there were no direct flights between Cancún and a Guatemalan airport, officials said Federal Bureau of Investigation agents were able to detain Gomez once he landed in Miami on a connecting flight. Information on his lawyer wasn't immediately available.

Eugene Colley made his fortune with more than 100 McDonald's restaurants.

"The murder scene was horrendous", Westchester County District Attorney Anthony Scarpino said.

The family lived in an area of extreme wealth where horse farms dot the landscape.

Investigators quickly ruled out Colley's multimillionaire husband, Eugene Colley, 88, as a suspect, saying there was no history of domestic violence at the address.
